Not the immediate plan, the putting-the-cop-funerals-in-the-rear-view-mirror plan, just to get back to business as usual — the one laid out in Monday’s embarrassingly defensive, revisionist, snark-on-the-media One Police Plaza press conference.

No, the long-term plan — the one that demonstrates to a city shocked to its core by the ambush assassination of two young cops that Mayor de Blasio fully understands the role he played in Saturday’s tragedy.

Which was substantial, even if indirect and beyond doubt unintentional.

The mayor took time to visit grieving families yesterday, and delivered soothing words at a Midtown luncheon. And he later said that he’ll be attending the ­officers’ funerals.

All well and good — indeed, all well and necessary. But it’s insufficient to the challenge now before de Blasio, now at the end of his rookie year, which is to restore the NYPD rank-and-file’s confidence in the city’s leaders — himself, in particular.

And to set about rebuilding the trust of the people in their police.

Certainly it was riding high in early 2013, when a Quinnipiac University poll gave the NYPD a 70 percent overall approval rating — which included a 56 percent thumbs-up tally from African-Americans.

Then de Blasio adopted what amounted to a one-plank public-safety campaign platform — embracing US District Court Judge Shira Scheindlin’s “stop-and-frisk” decision that effectively painted the NYPD as irredeemably racist — and riding it to a long-shot mayoral win.

Whereupon he translated her findings into municipal policy — incorporating the presumption of racist policing into operating doctrines citywide.

This set a tone, to put it mildly; by last July, when Eric Garner died after resisting arrest on Staten Island, City Hall and the cops were at daggers’ points and the scene was set for an astonishing demonstration of disrespect:

Scores of cops spontaneously turned their backs on the mayor Saturday night as he left the Brooklyn hospital where the bodies of the two assassinated officers lay.

It was an unprecedented act, betraying a rupture too profound to be repaired by words. But repaired it must be, for otherwise the city will become, once again, ungovernable.

But how? Right now, the burden is on de Blasio. He has yet to make clear that he understands the role police properly play in a civilized city — that there’s no equivocating on matters of moral authority in times of crisis.

Which is precisely what the mayor did last summer when he effectively granted Al Sharpton equal status with Police Commissioner Bill Bratton in the wake of Garner’s death.

That can never be undone, of course. But de Blasio can take concrete, constructive steps to set things right. Or, at least, to move in that direction. He can:

Instruct city lawyers to revisit the Scheindlin “stop-and-frisk” decision — so egregious that she was rebuked by a three-judge appeals court, before de Blasio said he didn’t care and accepted the ruling anyway.

Cut Sharpton loose. That is, make it clear that the Rev’s days as a policy-maker in the de Blasio administration are over.

Announce that the demonstrators’ free reign in the streets of New York is also history — that they’ll have access to the same public spaces as everybody else in the city, but that the boulevards and bridges are now and forever off-limits.

Make it clear to CUNY Chancellor James B. Milliken that the thuggish poetry professor arrested after “allegedly” attacking cops on the Brooklyn Bridge will not be welcome back into his Baruch College classroom at least until the charges against him have been prosecuted.

Similarly, make the Service Employees International Union pay a price for the arrest of one of its organizers in connection with that same cop-beating. SEIU and de Blasio have been tight as ticks for years; the union has been a prime sponsor of the protests that led to Saturday’s murders, and the mayor has stocked his senior leadership with SEIU operatives. He needs to fire a couple as a declaration of independence.

All of this would be symbolic, of course — meant to send a course-correcting message.

That is, the old symbols — the embrace of a race-obsessed judge’s dictums to gain political advantage; the Sharpton idolatry; the acceptance of chaos in the streets as the new normal — are now defunct.
But little steps for little feet.

Bill de Blasio needs to make it clear that from now on, the men and women of the NYPD will be treated as partners — not pariahs — in the governance of New York City.
